Your 3-Month-Old Baby's Development & Milestones

Ever wondered what’s going on in your baby’s mind? We take a glimpse into the world through the eyes of a 3-month old…

At around this age your baby will begin to be able to tell the difference between themselves and the rest of the world. Your little one is also likely to stay awake for slightly longer periods during the day. This gives them time to take in and learn from their surroundings.


Your baby’s hand eye coordination is just starting to develop. Baby’s hands can now open and shut. You may find your baby is able to take a swipe at a dangling toy or even grab a toy and put it in his mouth. He will begin to notice the difference between hard and soft too. Your little one is also rapidly gaining confidence moving his limbs and holding up his head.

Sound and vision

Baby’s hearing and vision are rapidly improving. You may notice your baby enjoys listening to music or turns his head at the sound of your voice. Visually, your baby will enjoy looking at bright colors because of the sharp contrasts. Your little one may also start to notice his own reflection in the mirror and will be fascinated by faces


While actual words are still a little way off, your baby is discovering his voice. Listen for contented coos, happy squeals and general babble. Encourage your baby’s interest in sound by singing, reading and talking to him.

Coming up

During the next few months your baby will hone and develop these basic skills. Soon he will be able to grab a toy and bring it up to his mouth. He will also begin to understand how one action can lead to another.
